Xi Ruoyao 7220b2446e x86/mm: Don't disable PCID when INVLPG has been fixed by microcode
commit f24f669d03f884a6ef95cca84317d0f329e93961 upstream.

Per the "Processor Specification Update" documentations referred by
the intel-microcode-20240312 release note, this microcode release has
fixed the issue for all affected models.

So don't disable PCID if the microcode is new enough.  The precise
minimum microcode revision fixing the issue was provided by Pawan
Intel.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
